Point. Bought mine and my wife's from GMG, but we paid only $45 apiece - so I'm willing to wait two extra days for that level of savings.I bought the standard edition and have 5 days early access. (playing right now) If you bought standard edition from the ESO site you get 5 days. If you bought it anywhere else, it is 3 days unless you buy the imperial edition.
Please let me know their answer I am having the same issue, was advertise as 5 days and now I am on an early 3 days instead.
